Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a driver's seat device for a tractor.

[0002]

[Prior art]

 The tractor includes a riding tractor having a driver's seat, and the driver's seat is fixed to the floor.

[0003]

[Problems to be solved by the device]

 For example, when a single-use earthen plate plow is attached to the rear part of the tractor and plow work is performed, the gravel soil plowed by the plow is usually turned to the right, The wheels on the right side of the tractor will fall into the ditch, and the plow will tilt the tractor to the right. At this time, the driver's seat is fixed, so the driver leans to the right along with the tractor. Therefore, there is a problem that the ride is uncomfortable and the work is difficult.

Therefore, an object of the present invention is to consider so that the driver can take a posture that facilitates work when the tractor is tilted.

[Means for Solving the Problems]

 The technical means taken by the present invention to achieve the above-mentioned object is that, in a tractor having a driver's seat 13, the driver's seat 13 is supported so as to be capable of changing its orientation around a vertical axis.

[0006]

[Action]

 When performing work such as plow work with the tractor 1 tilted to the right, the direction of the driver seat 13 is changed obliquely to the front right around the vertical axis. Then, the riding comfort becomes good and the work becomes easy.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIG. 3, 1 is a tractor, 2 is its vehicle body, and the vehicle body 2 is mainly constituted by directly connecting an engine, a clutch housing, a mission case and the like. An integrated cabin 3 is mounted on the rear of the vehicle body 2.

The cabin 3 is mainly composed of a pair of left and right front columns 4, a rear column 5, an intermediate column 6, and an upper frame 7 attached to the upper ends of the columns 4, 5, 6 and the like. It has a cabin frame. Doors 8 are attached to the left and right sides of the front of the cabin frame, side glass 9 is fitted on the left and right sides of the rear upper part, rear wheel fenders 10 are fixed on the left and right sides of the lower rear part, and a roof 11 is installed on the upper side. Is attached, and a floor plate 12 formed of a steel plate is attached to the bottom. The front glass is attached to the front and the rear glass is attached to the rear. A driver's seat 13 is arranged between the rear wheel fenders 10, and a steering wheel 14 is provided in front of the driver's seat 13.

As shown in FIGS. 1 and 2, on the right side of the driver's seat 13, operation levers 15 and 16 for auxiliary control valves, a hand accelerator lever 17, a hydraulic device operation lever 18 for raising and lowering a working machine, and a ground are provided. The operation levers such as the live switching lever 19, the PTO clutch valve operation lever 20 and the main and auxiliary shift operation levers (not shown) are centrally arranged, and these operation levers are located on the inner surface of the rear wheel fender 10. It is mounted and supported via mounting plates 21, 22, 23, etc.

The bases of the operation levers are covered by a shift cover 24. The shift cover 24 includes a side cover 25 that surrounds the left side and the front of the base of the operation levers, and an upper cover 26 that surrounds the upper side. Become. The side cover 25 is made of a plate material or the like in which a sheet-shaped covering material formed by vacuum forming a foamed rubber material is superposed on the surface of an iron plate, and is provided from the front to the rear of the driver seat 13 and the upper cover 26. Is made of a resin plate such as ABS resin, and guide grooves for the operating levers are formed. The lower portion of the side cover 25 is fixedly attached to the floor plate 12 via a stay, and the upper cover 26 is fixedly supported by the mounting plates 22 and 23 via the mounting brackets 27 and 28, as shown in FIG. The side cover 25 and the upper cover 26 are joined by a resin clip or the like.

The rear portion of the floor plate 12 is formed higher than the front portion in order to avoid the hydraulic device for lifting the working machine provided on the rear portion of the vehicle body 2. As shown in FIGS. An opening 29 for inspecting the lower part thereof is formed in. The opening 29 is closed by a cover plate 30, and the rear end of the cover plate 30 is attached to the rear part of the floor plate 12 by a hinge 31 so that inspection work or the like can be performed from the front side. Reference numeral 32 is a reinforcing member for reinforcing the periphery of the opening 29 and mounting the cover plate 30 thereon.

A rectangular swivel plate 33 is provided on the lid plate 30, and a driver's seat 13 is fixedly mounted on the swivel plate 33. Then, when the lid plate 30 is opened, the seat belt 36 is hooked on the operation handle device 37 for performing the expansion / contraction operation of the lift rod. The swivel plate 35 is supported by a plurality of balls 34 provided on the lid plate 30, and the right front corner portion is supported by a support shaft 35 having a vertical axis. It is supported rotatably around the axis of the support shaft 35. Further, as shown in FIG. 4, an arcuate guide groove 38 centered on the support shaft 35 is formed on the swivel plate 33, and engaging pins 41 provided on the cover plate 30 are provided at both ends of the guide groove 38. Are formed with engaging grooves 39, 40 which are selectively engaged with each other.

The engagement pin 41 can be operated to be disengaged from the engagement groove 39, 40 or to be engaged with the engagement groove 39, 40 by an operation lever (not shown). Then, the engagement pin 41 is engaged with one of the engagement grooves 39 to restrict the rotation of the swivel plate 33 around the support shaft 35, whereby the driver's seat 13 is held in the forward posture, and the other engagement member is held. By engaging the dowel groove 40, the driver's seat 13 is held in a turning posture facing diagonally forward right, and when the tractor 1 leans to the right when plowing, By changing the orientation of the seat 13 to change the posture, the driver's posture can be improved.

Further, in the present embodiment, the center of rotation of the driver's seat 13 is located on the right front side because the driver's seat 13 is located in the center of the tractor 1 in the left-right direction and the right side of the driver's seat 13 Since the bar 24 is present, the driver's seat 13 and the shift cover 24 are close to each other, and when the driver's seat 13 is rotated around the center, the armrests or seats of the driver's seat 13 interfere with the shift cover 24 and cannot rotate. Because. Therefore, as long as the driver's seat 13 does not interfere with others, the center of rotation may be located anywhere and the direction of rotation may be changed to the left.

As shown in FIGS. 8 and 9, the rear column 5 of the cabin 3 is covered with a cover member 42, and the lower portion of the cover member 42 is a stud for supporting the gas damper 44 that holds the rear glass 43 in an open state. It is fixed by 45. In FIGS. 10 to 12, reference numeral 46 denotes a sun visor, and a mirror 47 is provided on the rear surface of the sun visor 46 and also serves as a room mirror. Therefore, by storing the visor 46 in the storage recess 49 of the inner roof 48, it is taken into consideration that the rearview mirror does not obstruct the forward field of view in a work that places importance on the forward field of view.

[0016]

[Effect of device]

 According to the present invention, since the driver's seat 13 is supported so as to be capable of changing its orientation about the vertical axis, the orientation of the driver's seat 13 can be adjusted when the tractor 1 is tilted to the right in plow work, for example. By directing the vehicle to the diagonally right front, the driver's posture is improved, and work is facilitated.
